BERLIN -- A Vermont prison inmate who was brought to a hospital for treatment escaped and was missing for less than three hours before authorities caught up with him.

Police said 28-year-old Jonathan Henry of Marshfield had been jailed on an aggravated assault charge last month in East Montpelier. He was brought to Central Vermont Hospital on Tuesday from the Northeast Correctional Complex in St. Johnsbury.

Police said Henry escaped at about 5 p.m. He was taken into custody without incident at about 7:30 p.m. off of U.S. Route 302 near the River Run mobile home park in Berlin.
